Very good image quality, Improved high ISO performance; Improved handling; Faster 8 fps burst mode; Burst rate no longer slows down with RAW files; Improved buffer depth.
Soft corners at wide angle; No viewfinder; No 4K video; Mediocre battery life; Sluggish buffer clearing; Continuous AF struggles on fast subjects.
Read our Canon G7X Mark II Review

Fantastic image quality; Improved dynamic range over its predecessor; Very good high ISO performance; Much improved real-world AF performance; Class-leading burst rates, even with RAW; Improved 5-axis in-body image stabilization; Better 4K video quality; 1080/120fps video; Dual card slots; Significantly better battery life.
